means for facilitating the removal of said caps from the receptacles.

It is adapted for use whether the receptacles are sealed with a mechanical seal such as a locking seal, or a friction seal, and also for receptacles in which the contents is sealed in a vacuum.

In the drawings in which similar letters refer to similar parts Figure 1 illustrates my improved sealing cover or cap in position on a jar; Fig. 2 is a cross-section of Fig. 1; and Figs. 3, 4, 5 and 6 show my in vention used in connection with bottles or jars in which the neck of the bottle or top of the jar are of different form;

In the drawings in which similar letters refer to similar parts, A represents the jar which in the form shown is that of a small jelly glass, but my invention is equally suitable for use in connection with any jars, bottles or other receptacles. B is a cap preferaibly made of thin metal and provided with a downwardly projecting flange C which is formed into an annular beading provided on the upper side with a groove D and a top E, a downwardly projecting side F and an inwardly projecting lower member G. Within this annular beading I place a gasket, preferably of rubber, although other similar suitable material may be used. This gasket H is held in place within the annular beading by the metal which formsv the groove C providing an inwardly projecting lip, as shown, thereby compressing the gasket between the lower member G of the heading and the inwardly projecting lip. I prefer to make the inwardly projecting member Gr of sufi'icient length so that the pressure on the gasket between the inwardly projecting lip and the member G will be exerted on the fiat side of the member G and not on the inner edge.

Within the annular beading I place a rip Specification of Letters Patent.

strip I which passes substantially around the cover between the'gasket H and the inner face of the downwardly projecting side F of the beading through which one end of the rip strip I, which is made of metal, projects. This rip strip I may be made the width of the downwardly projecting side F of the beading, or of a width considerably less than the downwardly projecting side F, but I find that the operation of the rip strip in cutting the metal forming the side F of the beading is facilitated when the rip strip is of a width substantially the same as the length of the inner face of the side F so that the sides of the rip strip tend to engage with the top and bottom corners of the beading at which point the metal forming the beading is usually weakened somewhat by the bending operation, thereby makes it easier to permit the rip strip to perform its function.

The operation of sealing a jar or receptacle with my improved cap is to compress the annular beading by pressure brought to bear on the upper side E of the beading to form the groove D, and on the lower member G so that a portion of the gasket H is forced out of the heading into contact with the receptacle to be sealed thereby creating a frictional or mechanical seal. When used without the rip strip I, access to the conby the insertion of an instrument between the glass and the lower member G of the annular beading so as to press the lower 'tents of the receptacle may be readily had projects from the outer side of the bead- I ing of the cap, and byturning the key the rip strip cuts the metal forming the side F of the heading. After a sufiicient amount of the metal has been cut away and wound on the key with the cutting strip the top of the cover may be raised, or, if desired, removed entirely leaving a portion of the beading secured to the jar which may readily be removed as the cutting away of the side F releases the gasket and permits it to assumeits normal condition which will enable it to be easily removed from the jar.

In the modifications shown in Figs. 3,

4, 5 and 6, the construction of my improved cap or cover is substantially the same; The operation of sealing the-jar is substantially the same as that described above, but the construction of the neck of the bottle or the top of the jar is different in the following respects: 3 the sides of the jar or bottle are substantially parallel so that the seal is a friction seal as distinguished from a locking sealthat is the gasket H engages withthe receptacle A, and holds the cover in place by friction. In Fig. 4 a shoulder is provided at the top of the receptacle. In Fig. 5 a groove is provided. In Fig. 6 the top of the receptacle is bell-shaped. In Figs. 2, 4, 5 and 6, therefore, there is a locking sealthat is the cap is locked into position as distinguished from a friction seal as in Fig. 3.

located within the beading in contact with the rip strip and holding the strip positioned Within the beading and out-of contact with the container.

In testimony whereof I have'signed my name to this specification in the presence of two subscribing WItIIBSSQS.
